Chemistry for site plant and equipment

Products for mixers, batching plant, moulds and tools: removing concrete build-up, cement laitance and bitumen, plus corrosion protection for equipment standing idle.

This view contains only the products assigned to this surface.

Type of deposit
Concrete, cement laitance and bitumen come off with three different products - one will not substitute for another.
When to apply
A preventive product goes on before work or at the end of a shift. A cleaning product dissolves what has already stuck.
Material compatibility
Manufacturers state plainly what the product does not attack: lacquer, seals, rubber, glass.

5 products

This category is not about surfaces. The products gathered here are formulated for metal, moulds and tools, where the deposit is thicker and the substrate - lacquer, rubber, seals - is often more sensitive than concrete.

Three different deposits

  • Concrete build-up - bonded residue on a drum, a mould, a scaffold.
  • Cement laitance, cement and lime - the thin, hard film of everyday work.
  • Bitumen, asphalt and tar - these need a solvent, not an acid or an alkali.

Preventive or remedial

Some products work in two modes. Applied before a production run they make it harder for concrete to stick; applied after a shift they dissolve the deposit overnight, so it washes off with water in the morning. That is usually cheaper than chipping off bonded concrete once a quarter.

Corrosion protection stands apart: a film applied to equipment stored or transported in damp surroundings, at the end of a season or before despatch.

Questions before you choose

Can I use these products on block paving?

Do not assume so. They are formulated for metal and equipment, not for absorbent mineral substrates. For surfaces, use the products in "Cleaning and restoration".

Does the product need neutralising after rinsing?

It depends on the product. Where the manufacturer states that no neutralisation is needed, we have it in the technical data. Where there is no such statement, we do not assume one on the manufacturer's behalf.

Are these corrosive substances?

Manufacturers describe them as not classified as corrosive, or as irritant only - and we give that classification on every product. Gloves and eye protection apply whatever the classification.
